Hi, I have written a traffic 2.5 dci 150 MY2007 with Original Galletto to remove the DPF.
Supported Injectors and everything OK.
When the engine starts, after one second the engine stops.
?Immo problem ?,
NO, Only:
DF053 Rail Pressure Regulation Function.
1.DEF. upper limit exceeded.
Freeze data:
Engine: 611r.p.m.
Rail Sensor: 1782,70bar (max. sensor value)
Demand ecu rail pressure: 311bar
Original file is written by EOBD again. Same error.
I have opened the ecu to read by BDM. I have checked the flash (comparing it with another dump) and I have not seen anything wrong.
Can be a problem E2prom or ecu malfunction? Coincidence?
I tried with another rail pressure sensor. Same error, same values.
Now I need to try another ecu or replace high pressure regulator valve.
Does anyone know a similar problem?
Regards
